I'm not sure how the bridge initialization is supposed to work with TB3
security. But, I would guess that the dock needs to be authorized first
before the PCIE bridges can be initialized.
Since the BIOS is not handling the TB3 authorization, it might not be
able to access the bridges. So the task
Hi, the BIOS is expected to configure the PCI bridges leading to the TBT
controller but it does not seem to do that:
[3.725792] pci :06:00.0: bridge configuration invalid ([bus 00-00]),

Thunderbolt support for PCs is included in v4.13-rc1 and later kernels.
Do you have a possibility to try the latest mainline kernel?
Note the userspace support is not yet ready so you need to authorize
device manually. See for example:https://www.kernel.org/doc/html/latest

Did this issue start happening after an update/upgrade? Was there a
prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v4.12 kernel[
